Appfication filed August '7, 1907. Serial No. 387,452.

To all whom it may concern:

Be it known that I, GEORGE E. HULsE, re-

siding at Newark, in the county of Essex and State of New Jersey, have invented certain new anduseful Improvements in Fluid- Pressure-Regulating Apparatus, of which the following is a full, clear, and, exact description, such as will enable others skilled in the art to which it appertains to make and use the same. r

This invention relates to lighting apparatus and is more especially directed to gas lighting apparatus adapted for use in railway cars or similar structures. I

One of the objects of the invention is to provide new and improved means whereby the gas pressure to the lamps or other gas utilizing devices of railway cars may be varied at will.

Another object of the invention is to provide in a gas lighting system ofthe above character a plurality of devices for regulating the gas pressure and having means whereby one of said regulating devices may be cut off or thrown in at will without affectingin any way the operation of the other regulating device.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction,- combinations of ele ments, and arrangements of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the following claims. 'l I In the accompanying drawings wherein is illustrated one of the-various possible embodiments of my invention, Figure 1 is a view in elevation thereof.- Fig. 2 is a ver-.

tical sectional view of the mechanism illustrated in Fig. 1. 4

Similar reference characters refer to similar parts in both views of the drawings.

Referring now to the drawings, 1 indicates the casin of a gas regulator into which leads con uit 2, said conduit being adapted to be connected with a gas tank beneath a railway car or with any suitable source of gas supply. Extending from regulator 1 is a conduit 3 adapted to conduct gas therefrom to another gas re ulator, the casing of which is shown in 4. xtending from regulator 4' is a conduit 5 which leads into a fitting 6 and from this fitting extends a conduit 7, the latter being adapted to be connected with the lamps of a railway car or other gas utilizing devices. A conduit 8 leads from conduit 3, extends about regulator 4 and leads into fitting 6. At this point it may be noted that the regulators .inclosed in the casings 1 and 4 are adapted to cut down the gas pressure furnished by the supplying means in dilferent degrees,

that is, the regulator in casing 1 in the present instance is adapted to cut the pressure down to one pound, while the regulator in casing 4 will cut the same down to one-half pound pressure. It will be understood, of course, that the ultimate pressure reaching the lamps when both'regulators are in the conducting circuit will be that furnished by regulator 4 or the light pressure regulator.

Fitting 6 is provided with a three-way cock 9 adapted when adjusted to one position to shut oil the flow of gas from conduits 5 and 8 and when adjusted in a second position to shutoff the flow of gas from conduit 5 without affecting the flow through the lower regulator byway of conduit 8 to the lamps, and when adjusted to a third position to shut off the flow through conduit 8 while permitting the flow through both regulators to the lamps through conduit 5.

Vhile any suitable type of regulator may be employed in this relation, in Fig. 2 I have shown sectionally a preferred embodiment thereof, the regulators shown being of the diaphragm type. The diaphragms of these regulators are adapted, through lever mechanisms 10 and 11, to operate valves 12 and 13, respectively, interposed in the intake ports of the regulators, suitable springs being provided to interpose .a resistance to the distending movements of the diaphragm.

No claim is made herein to the particular construction of the regulators shown, the mechanism shown in one thereof being shown, described and claimed in my application, Seriyal Number 394,347, filed September 24, 190 i Having thus described my invention the operation thereof which should to a large extent be obvious, is substantially as follows:

I found it desirable, however, under certain conditions, as when it is desirable to diminish the amount of illumination within the car which can be effected by diminishing the flow of gas through all the lamps, to provide means whereby a low pressure regulator may be thrown into the gas connecting circuit. This operation may be effected by turning the three-way cock 9 to such position as will shut off the flow of gas through conduit 8 and open conduit 5 whereupon gas will flow through both regulators to the lamps, the pressure being cut down in accordance with the adjustment of regulator 4-. Thereafter the gas pressure supplied to the lamps will be that allowed by the low pressure regulator. It will accordingly be seen that I have provided a regulating apparatus well adapted to attain among others all the ends and objects above enumerated, in an exceedingly simple yet eiiicient manner whereby the lamps of a railway car or similar structure may be operated in a turned-down condition without danger of the same being blown out or ex tinguished by excessive pressure in the supplying means. Moreover the pressure to the lamps is accurately regulated whether they are supplied with low or high pressure from the source of gas supply.

As many changes could be made in the above construction and many apparently Widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is:
